I've eaten sea urchin eggs directly from sea urchins

What does THAT mean? You were snorkeling somewhere and came upon a female sea urchin and....blechhhh.

Yup! That's exactly what it means. I opened up some female sea urchins after diving for them with my knife and ate the eggs right off the knife. Actually it's quite good and despite your revulsion, it is a great survival tool if you are ever stranded on an island.
